-# Fedora bootc base images
+# Debian bootc base images

-Create and maintain base *bootable* container images from Fedora packages.
+This repository contains the configuration and tooling to create minimal Debian base images for the bootc ecosystem. These images serve as templates that bootc-image-builder can use to create bootable disk images.

-## Motivation
+## Overview

-The original Docker container model of using "layers" to model applications has
-been extremely successful. This project aims to apply the same technique for
-bootable host systems - using standard OCI/Docker containers as a transport and
-delivery format for base operating system updates.
+Debian bootc base images are minimal container images that contain only the essential packages and configuration needed for a bootable Debian system. They are designed to work with the bootc ecosystem tools like `bootc-image-builder` and `osbuild`.

-## Building images
+## Architecture

-The current default user experience is to build *layered* images on top of the official
-binary base images produced and tested by this project. See the documentation[5] for more info.
+The repository follows the same architecture as Fedora's bootc-base-images:

-You can build custom base images by forking this repository; however,
-<https://gitlab.com/fedora/bootc/tracker/-/issues/32> tracks a more supportable
-mechanism that is not simply forking. For more information see[6].
+- **Minimal templates**: These are minimal base images, not complete populated systems
+- **Component-based**: Each image type (minimal, standard, iot) is composed of reusable components
+- **OSTree-ready**: Images are designed to work with OSTree for atomic updates

-## Build process
+## Image Types

-Building the images in this repo can be done with `podman build`, but
-note the build process uses a special podman-ecosystem specific mechanism
-to create fully custom images while inside a `Containerfile`.
-You need to enable some privileges as nested containerization is required.
+### Minimal (`debian-minimal`)
+- Essential boot infrastructure
+- Basic system tools
+- OSTree support
+- GRUB bootloader
+
+### Standard (`debian-standard`)
+- Everything from minimal
+- Additional system utilities
+- Network tools
+- Development tools
+
+### IoT (`debian-iot`)
+- Everything from minimal
+- IoT-specific packages
+- Container runtime support
+- Monitoring tools
+
+## Building Images
+
+### Prerequisites
+
+- Podman with fuse support
+- Build tools (apt-ostree, selinux-policy-default, python3)
+
+### Basic Build

 ```bash
-podman build --security-opt=label=disable --cap-add=all \
-  --device /dev/fuse -t localhost/fedora-bootc .
+# Build with default apt-cache-ng proxy
+./build.sh
+
+# Build without proxy (direct to Debian repositories)
+./build.sh ""
+
+# Build with custom proxy
+./build.sh "http://your-proxy:3142"
 ```

-See the `Containerfile` for more details. This builds the default `standard` image.
-
-## Fedora versions
-
-By default, the base images are built for Fedora rawhide. To build against a
-different Fedora version, you can override the `FROM` image used to obtain the
-Fedora repos and dnf variables. E.g.:
+### Manual Build

 ```bash
-podman build --from quay.io/fedora/fedora:41 ...
+# Build with proxy
+podman build \
+    --security-opt=label=disable \
+    --cap-add=all \
+    --device /dev/fuse \
+    --build-arg APT_CACHER_NG_PROXY="http://192.168.1.101:3142" \
+    -t localhost/debian-bootc:minimal \
+    .
+
+# Build without proxy
+podman build \
+    --security-opt=label=disable \
+    --cap-add=all \
+    --device /dev/fuse \
+    --build-arg APT_CACHER_NG_PROXY="" \
+    -t localhost/debian-bootc:minimal \
+    .
 ```

-### Deriving
+## Apt-Cache-NG Proxy Configuration

-You are of course also free to fork, customize, and build base images yourself.
-See this page[6] of the documentation for more information.
+The build system supports apt-cache-ng proxy configuration for faster builds and offline development:

-## Tiers
+### With Proxy (Default)
+```bash
+./build.sh "http://192.168.1.101:3142"
+```

-At the current time, there is just one reference base image published
-to the registry. Internally the content set is split up somewhat
-into "tiers", but this is an internal implementation detail and may change
-at any time.
+### Without Proxy
+```bash
+./build.sh ""
+```

-It is planned to rework and improve this in the future, especially
-to support smaller custom images. For more on this, see
-[this tracker issue](https://gitlab.com/fedora/bootc/tracker/-/issues/32).
+### Custom Proxy
+```bash
+./build.sh "http://your-cache-server:3142"
+```

- **standard**: This image is the default, what is published as
-  <https://quay.io/repository/fedora/fedora-bootc>
- **minimal**: This content set is more of a convenient centralization point for CI
-  and curation around a package set that is intended as a starting point for
-  a container base image.
- **minimal-plus**: This content set is intended to be the shared base used by all image-based
-  Fedora variants (IoT, Atomic Desktops, and CoreOS).
+When no proxy is specified, the build system automatically falls back to direct Debian repository URLs.

-**standard** inherits from **minimal-plus** and **minimal-plus** in turn inherit from **minimal**.
+## Debian Versions

-All non-trivial changes to **minimal** and **minimal-plus** should be ACKed by at least
-one stakeholder of each Fedora variant WGs.
+- **13 (Trixie)**: Stable release (default)
+- **14 (Forky)**: Testing release
+- **00 (Sid)**: Unstable/rolling release

-### Available Tiers + Versions
